C# - LINQ Statements with OR clauses

Question

I am trying to use LINQ to return a list of tasks that are in one of three states. These states are:

10 - Completed 11 - Incomplete 12 - Skipped

The state is available through a property called "TaskStateID". I can do this in LINQ with just one state as shown here:

var filteredTasks = from task in tasks                     select task;  // Do stuff with filtered tasks  string selectedComboBoxValue = GetFilterComboBoxValue(); if (selected ComboBoxValue == 3) {   filteredTasks = filteredTasks.Where(p => p.TaskStateID == 10); // How do I use an 'OR' here to say p.TaskStateID == 10 OR p.TaskStateID == 11 OR p.TaskStateID == 12 } 

As shown in the comment above, how do I use an 'OR' in a LINQ statement to say p.TaskStateID == 10 OR p.TaskStateID == 11 OR p.TaskStateID == 12?

Thank you

Use the OR (||) operator:

filteredTasks = filteredTasks.Where(p => p.TaskStateID == 10 ||                                           p.TaskStateID == 11 ||                                           p.TaskStateID == 12);
